Can someone tell me why I am getting errors? What happened to my total?
The only issue I can see is that you perhaps have not added a formula to your 'Total' line item.
Easiest way to ensure that the total is summing up all the associated line items is to assign the 'Total' line item as the parent of the other line items in the blueprint. You will see the 'Parent' column in the blueprint of the module if you scroll to the right. Select from the drop down the 'Total' line item for each of the other line items. The formula will auto populate with the current sum.
That's weird. What's the summary of your "Total" line item
